Abstract

A process for producing plasticizers in which a phthalic acid having the CAS Nos. 111381-89-6, 111381-90-9, 111381-91-0, 68515-44-6, 68515-45-7 and 3648-20-7, the formed plasticizers and a method of increasing the plasticity of a plastic product.

Claims

exact text as granted — not AI-modified
1. A dicarboxylic acid diester mixture, selected from the group consisting of:
 a cyclohexane-1,2-dicarboxylic acid di(isononyl) ester mixture, obtained by hydrogenating the di(isononyl)phthalate mixture having the Chemical Abstracts registry number (“CAS No.”) 68515-48-0;  
 a cyclohexane-1,2-dicarboxylic acid di(isononyl) ester mixture, obtained by hydrogenating the di(isononyl)phthalate mixture having the CAS No. 28553-12-0, based on n-butene; and  
 a cyclohexane-1,2-dicarboxylic acid di(isononyl) ester mixture, obtained by hydrogenating the di(isononyl)phthalate mixture having the CAS No. 28553-12-0, based on isobutene.  
 
     
     
       2. A dicarboxylic acid diester mixture as claimed in  claim 1 , selected from the group consisting of:
 a cyclohexane-1,2-dicarboxylic acid di(isononyl) ester mixture, obtained by hydrogenating the di(isononyl)phthalate mixture having the CAS No. 28553-12-0, based on n-butene; and  
 a cyclohexane-1,2-dicarboxylic acid di(isononyl) ester mixture, obtained by hydrogenating the di(isononyl)phthalate mixture having the CAS No. 28553-12-0, based on isobutene.  
 
     
     
       3. A method of increasing the plasticity of a plastic product which comprises admixing to the plastic a plasticizing amount of at least one of the dicarboxylic acid diester mixtures defined in  claim 1 . 
     
     
       4. A method of increasing the plasticity of a plastic product which comprises admixing to the plastic a plasticizing amount of at least one of the dicarboxylic acid diester mixtures defined in  claim 2 . 
     
     
       5. A plastic product which comprising a plasticizing amount of at least one of the dicarboxylic acid diester mixtures defined in  claim 1 . 
     
     
       6. A plastic product which comprising a plasticizing amount of at least one of the dicarboxylic acid diester mixtures defined in  claim 2 . 
     
     
       7. The method of  claim 3 , wherein said plastic product is PVB. 
     
     
       8. The method of  claim 3 , wherein said plastic product is PVC. 
     
     
       9. The method of  claim 4 , wherein said plastic product is PVB. 
     
     
       10. The method of  claim 4 , wherein said plastic product is PVC. 
     
     
       11. The plastic product of  claim 5 , wherein said plastic product is PVB. 
     
     
       12. The plastic product of  claim 5 , wherein said plastic product is PVC. 
     
     
       13. The plastic product of  claim 6 , wherein said plastic product is PVB. 
     
     
       14. The plastic product of  claim 6 , wherein said plastic product is PVC.
